It would be nice to be able t play around with the color of crepuscular rays using the scripting commands getInscatteringIntensity and setInscatteringIntensity from VBS3. The command would be global and JIP compatible.
The uses for this would include making more scenic pictures, add to the visual simulation of nukes, and allow for many other uses for the new crepuscular rays the RV4 engine gives us.
